It will all depend on your motherboard on UD5/7 I can run 2133CL7 at 1.7, 2200 CL8 at 1.7; on M4E I need 1.72Vdimm... on the other Asus boards I own Hypers just don't work properly over 1866 divider... ( I can run them 1866CL6 at 1.65Vdimm all day, for 2133Mhz CL8 it's not even stable at 1.76Vdimm)
Purely bios related...
Question : Why do some overclockers switch into d*ckmode when money is involved
Remark : They call me Pro Asus Saaya yupp, I agree
my hypers can run 2133 8-8-8-24 1T on P867 Deluxe B3, i feel lucky.. coz i try 3 board P67 deluxe, only one that can run with my Hyper
For the hyper issues on some boards, the sticks aren't up to it. I have 6 GTX 2 sticks and only 4 of them run at 2133 CL7-7-7-21 on the Dlx B2 board, the other ones even fail at 7-8-7...(while that works on M4E and UD5/7) It's all up to good sticks ( no matter what they did on other platforms, SB is different ) as some do it at 1.68Vdimm, other ones need 1.72

soon or later we get bios from asus with "better memory compatibility"

Pulled these out of retirement to play on Sandy Bridge and P67.
Currently over 45min stable Prime95 x64 i5-2500k @ 4.8ghz, 7-10-7-27 74 1T DDR3 2133 1.65v.
Passed an hour stable.
My sticks must be inferior chips - doesn't like tRCD 9 at 2133 - has to be 10

mine (cpu@ stock for now)
hiwa had some 7-10-7 that could do 6-7-6... doesn't work for me @ 1.65v
using bios 1598... set vdimm to 1.65v exactly, full phase enabled ocp disabled... my real voltage seems to stay @ 1.66v,even sometimes when not @ load... it only reverts to 1.6501v when started from a cold boot though.
Try boot up @ 2133 6-9-6-24 with 1.76Vdimm and 1.14Vcsa
Hey did they change the IC on this kit? As i just got a kit and it reads 17600cl7d-4gbpis i see this kit was released back in P55 days, and on the package it says P67. you guys think its the same stuff or an IC change?
you sure?
mine came in the typical brown gskill box.. upper right hand corner there is a bluish green sticker that says "Engineered specifically for intel core i7 860/870 cpus" no p67.
Don't have pic of box, but here is a pic of the stick
Same?
Can you check if it does 7-9-7 because mine and it seems alot of others here can't... they can only do 7-10-7... tRCD has problems going down to 9... but they scale very well in frequency
if it can do 7-9-7 with rated volts, then ic might be different
I think you have to have pretty strong sticks to pull off 2133+ 7-9-7...
My 2133 7-10-7 kit has no problem doing 2000 7-9-6, at least on AMD.
Smile
my gskill 7-10-10 2200 can do 7-10-7 2250MHz fine and dandy, but cannot do 7-9-7 2133. Weird thing is that i have dominator gt 8-9-8 which can do 7-9-7 2133 just fine with 1.65v, but i need to loosen timings to 9-10-9 for 2250MHz (or of course increase voltage)
gskill 2250
dominator gt 2250
Dominator gt 2133 7-9-7
Don't be shy with voltage....
I jolted (for benching) my 2133 C8 Gskill with 1.75 for 2100 7-9-6-20 on AMD 990X whereas it benched @ 2222 6-9-6-24 with 1.82Vdimm on Intel P67
i was planning to test all my ram with 1.7+ volts but my maximus broke and now i have to wait for rma
1.82 ok for benching on p67? no dead chips you've experienced?
will be running chiller @ -20C only. ai tweak says -4C, but k probe by the block does say -17 to -11C at load
Powerchips are hard to predict, specs don't say much if the timings are rated at 9-11-9-27. My PIS kits both won't do 1070 7-9-7-24 at 1,65V, one does 7-9-9-24 as it is TRP-limited and not TRCD at these frequecies, both go up to bclk limit at 1150+ with 7-10-9-27 respectively 7-10-7-27 with 1,65v and less. So everything will show at testing, I prefer BBSE or hyper on SB anyway
mine seems to be entirely tRCD bound up to 1125 which is my current chip's blck wall.
it can do 7-10-7 with 1.65v. I do prefer bbse over psc, but the only ones i can find are the gskill trident 9-9-9 2000 ones. Do you think those are better than these psc chips?
and i've gone through 4 sets of hyper kits with no luck yet with getting them stable @ stock volts Still waiting for a gtx2 to pop up... linuxfan had adata 8-8-8 2200 but he caught me at a bad time (no money)
Itīs pretty hard to find good mems for SB, bad compability especially with hyper-ics and eol on nearly all good oc-ics and mems make things even harder. I has two sets of trident 2000 and one of ripjaw 2000 C9, all ran acceptbale, the ripjaws doing 1070 7-9-7, the trident 2000 dual doing 1095 7-9-7 and on the trident triple two sticks went above 1140 7-9-7 and one stopped at 1130 7-9-7 at 1,65V, all scaling with higher voltage. So itīs hard to predict hoe these will run, but all were good SB rams, even my 1600 C6-7-6 trident run easy above 1110 7-9-7-20. As I also have two sets of RipjawX 2133C8 which do 7-9-7 up to bclk-limit (1150 ram) with less than 1,65v and a couple of hyper kits that run on mini-asus as well as on ud5 I stopped testing a while ago, so thatīs all that I can say about memory on this awful and bugged platform^^
i had a two sets of 4gb trident 2000c9 they did 9-9-9 24 1100 @ 1.65v and i couldn't get cas down to 7 at anything 2k, but i think that had to do with the fact that i ran them with an evga p67 ftw which has memory issues.
Now as soon as my mive comes back from rma..
might grab me another set again.
thanks websmile.
EDIT: hopefully x79 will be better, i just wonder how quad channel will overclock..
i hope that memory compatibility issues will be fixed if and once ib comes out for 1155
